Resolved Issues
-
AGT-61779 [S1584382]: Null character added in the file after data encryption with
VMLFS
driverA CTE driver was incorrectly identifying certain files as sparse files, and therefore, not decrypting certain portions of the file. This has been fixed.
-
AGT-62791 [CS1593263]: CTE nodes are crashing on the latest CTE version (7.6.0.132), causing issues with the LDT Communication Group recovery
LDT over CIFS was locking code on the secondary agent after a method it called decided to free a lock. If another thread on the entire system had already allocated that same memory, then the reference count decrement corrupted their memory. The solution was to recognize that the lock was freed and to not decrement the reference count.
Known Issues
-
AGT-36370: The vorvmd.log reports an error message when guarding LDT over CIFS GuardPoint
CTE agent needs CIFS credentials to apply a GuardPoint on a CIFS share. This error message displays when the CTE agent is in the process of authenticating the user. This error can be safely ignored.
-
AGT-39189 | AGT-55063: CTE failed to unguard after changing to incorrect CIFS credentials
If a user has a CIFS guarded path, and tries to access it with invalid credentials, the unguard request fails. After this, if the user switches to valid credentials, the unguard request still fails.
Work-around
To successfully guard/unguard a CIFS path, use valid credentials.
-
AGT-48196: Microsoft DPM reports recovery creation failed when creating a recovery point after synchronizing data
Work-around
Perform a complete backup. Do not perform an incremental backup. The incremental backup does not work properly with LDT.
-
AGT-48580: Ransomware Protection gzip files in a directory can be mistakenly identified as ransomware
Intermittently, zip or unzip activity that occurs within a Ransomware Protection GuardPoint is identified as ransomware.
Work-around
Add the zip/gzip/winzip programs to the Ransomware Protection process exemption list in the CipherTrust Manager client profile.
-
AGT-48862: Stopping secfsd service does not unguard CIFS GuardPoint
Secfsd service is a critical service needed to perform Guard/Unguard operations. If this service is not running, CTE agent fails to unguard the CIFS GuardPoints.
Work-around
Manually disable the GuardPoint in CipherTrust Manager.
-
AGT-58577: Issues and limitations for Multifactor Authentication and Ransomware Protection co-existence
-
When Multifactor Authentication is configured and used in a Client Profile (OIDC or EntraID), Ransomware Protection fails to setup on the host.
-
When attempting to change the Multifactor Authentication profile to the default client profile, that also fails.
-
When an OIDC connection is associated with a client profile, CipherTrust Manager reports an error while creating a Ransomware Protection GuardPoint.
Note
Multifactor Authentication is not yet supported for a GuardPoint with Ransomware Protection with a CTE Agent. You can associate Multifactor Authentication with a CTE GuardPoint with no Ransomware Protection, and that should work normally.
Work-around
-
Remove the OIDC connection from the client profile.
-
Create another Ransomware Protection GuardPoint and re-associate the OIDC connection to the client profile after guarding succeeds.
-
-
AGT-61138: Guard a system UNC by Standard policy, files are shown as cipher-text format from local Windows explorer
Work-around
Only view the files using the UNC from the local system (
\\192.168.1.1\secrets
). Do not use Windows Explorer (e:\secrets
). -
AGT-63078: On Win 2019 Datacenter, no Register Host displays after installing v7.6.0.143. Also
Etray.exe
system error opens after rebooting Windows hostError message displays,
The code execution cannot proceed because
VCRUNTIME140_1.DLLwas not found. Reinstalling the program may fix this problem.
Work-around
Copy a valid
VCRUNTIME140_1.DLL
from another Windows computer.
